### ⚠️ Important Note About Stepper Motor Current
For the SKR-Mini-E3-V3.0, the `run_current` for x, y, z stepper motors has been reduced in the `printer.cfg`, because the standard current seems to make the steppers dangerously hot. You may have to increase the current, or if the motors are still too hot, you may have to decrease it.
💡 Although stepper motors can withstand upwards of 125C, they should at the most get hot to the touch (~55C), not *very hot*.
